WebLow-cost organic photodetectors have shown sensitivity levels comparable to those of inorganic photodetectors, but with response speeds generally limited to the megahertz range due to the low mobility of organic semiconductors. Here, we integrated organic–inorganic hybrid perovskite (OIHP) photoactive layers WebDec 1, 2024 · In the second part of this paper, we review several materials that provide an improved contact passivation in comparison to the implementation of dopant-diffused n + and p + regions, as used in most of today's industrial solar cells. These electron- and hole-selective layers largely suppress contact recombination and, at the same time, allow for … chur ringstrasse

WebJul 9, 2024 · The CB improves the perovskite crystal morphology. Meanwhile, PMMA passivates the defects between poly (3, 4-ethylenedioxythiophene)-poly (styrenesulfonate) (PEDOT: PSS) and perovskite layer, thus increasing the short-circuit current. Excitingly, we find that PMMA benefits the grain boundaries (GBs) of perovskite, which makes it more … Organic–inorganic perovskite materials have drawn tremendous attention for optoelectronic devices over the past decade, given their exceptional optoelectronic properties and use of low-cost precursor materials.1–4 By compositional engineering,5,6 optimization of the perovskite thin film … See more Ultra-thin PPX layers of thicknesses between 0.5 nm and 5 nm are deposited on the surface of the double-cation perovskite thin films via the CVD polymerization of … See more In this work, CVD polymerization is introduced as a novel technique to efficiently passivate the surface of polycrystalline perovskite thin films with ultra-thin PPX polymer … See more The authors gratefully acknowledge financial support of the German Federal Ministry of Education and Research (PRINTPERO, funding … See more M.
